Price indexes are an essential tool for the analysis of real output in the construction industry and for relative performance and productivity measures. They provide a succinct picture of the past and a useful framework for forecasting future developments. Government requires such price indexes as part of the information used in the development of its policies including support programs to provincial governments. These indexes are also used in construction contracts to adjust for cost fluctuations and inflation. It is however, a difficult task to obtain satisfactory indexes reflecting 'pure' price changes for construction. The units built are nonstandard and heterogeneous with large variations in quality, size, design and construction techniques. Consequently, there are many different types of indexes developed from information recorded in the construction industry.

This paper summarizes the various ways in which construction price indexes can be compiled, and examines and compares the performance of some of the indexes currently produced at Statistics Canada. It is hoped that the comparisons would permit an assessment of the various types of construction indexes examined for specific applications.

Help for sorting results

How are the results ordered?

The Sort by feature provides three options:

date – sorts results by release date starting with the most recent.

relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.

title – sorts results alphabetically.

Help for filters and search

How do I use the filters and the search box?

You can initiate a search by entering keywords or selecting filters (e.g., under Subject, etc.).

Filters can be used together or in any combination. Only 1 filter can be selected at a time, per section. Each time you select a filter, the page reloads.

Specified keywords and filters appear as “tags” above the search box after each filter selection or keyword entry. You can deselect any or all the “tags” to refine or clear your search.

To start a new search, click on the Clear all button above the search box or deselect each filter.

How do I refine my search?

You can enter keywords in the search box. It is not necessary to use “+” or “,” or “AND”.

You can delete some or all of the keywords from your search string.

Quotes around keywords limit the search to a specific phrase.

For example, “labour force survey” will limit results to products containing this phrase.

Use “or” between keywords to obtain results that contain one or more search terms.

For example, labour or­ force or survey will limit results to products containing any or all of these words.

How does the search work?

Search results are linked to terms ‘tagged’ to subjects, keywords, etc., or included in metadata fields such as title, description.

For example, when searching the term ‘Diseases’, all results with the word ‘Diseases’ in the title, description or tagged the subject appear.
